Every snowflake is unique. Using your name as snowflake DNA we have created a personal snowflake design for you.

Snowflakes are a form of fractal, complex mathematical shapes that are often found in nature.

The fractal pictures here were grown using growth rules that are repeatedly applied. The technique is known as Lindenmayer-Systems (or L-Systems for short) after biologist Aristid Lindenmayer who used them to study plants.

The rules can be very simple - it’s the repetition at different scales that creates the intricate form of fractals. From simple rules, great oak trees grow.

Happy holidays! See you in the new year.
